Title: Magnetic rail brake holder for rail vehicle - has sealed holes for rotating pins on carrier preventing transmission of bending moments
Inventor: KRIEGER HEINZ
IPC: B61H7/08
Filed: 1976-08-07
Abstract: The magnetic rail brake is held between axial bearings of the bogie and the holder is connected to axle bearing housing. No bending moments, caused by twisting of magnetic brake holder are transmitted to axle bearing housing. The magnetic rail brake carrier (2) has pins (7) at its both ends rotating in a hole of the holding component (9). The latter is in turn fastened on axle bearing housing. A flexible spacer (10) is inserted into the hole of the holding component. Entry of dirt is prevented by sealing lips on the holding component side with holes. The rotation of pins prevents transmission of bending moments.

Title: Serial pulse code combination generation - uses groups of pulses separated by fixed intervals transmitted to preselected sequence over single line
Inventor: MANSSON SVEN EBERT
IPC: H04W88/18
Filed: 1976-09-25
Abstract: A digital coding system involves the generation of groups of serial pulses separated by a fixed interval. The technique provides a virtually unlimited capacity for code combinations. For a system based upon a maximum of ten pulses within a group, a counter and selector stage are both based upon standard TTL decade counter modules, within the transmitter stage. When an activation switch is closed an oscillator is started to cause the counter states to change. The number of pulses in a group is determined by combining counter outputs in combinational circuitry. When the combinational circuit generates an output an interval circuit presets the counter and provides the necessary period between groups. The system is particularly suited to fixed sequence code combination transmissions.

Title: Propulsion system for low-speed aircraft or watercraft - has pressure energy motor supplied from reservoir and acting directly on hinged flaps with spring return
Inventor: RAEHMER HANS
IPC: B64D27/02
Filed: 1976-11-06
Abstract: The propulsion system comprises a pressure energy motor (1) supplied either from a reservoir alone or with an alternative supply from a pressure energy generating prime mover. The latter need only be sized for cruising power, short term additional requirements being met from the reservoir. There is direct drive from motor to a propeller, in the form of hinged parallel flaps (5) alternately pressed apart by the motor and brought together by spring (6) or additional motor-action. The propulsive effect is obtained during the latter movement, due to expulsion of ambient fluid.
Patent DE-2651492-A1 (DE)
Title: One-way electronic switch - has inductance to limit rate of current rise at switch-on and reduce power loss
Inventor: BOEHRINGER ANDREAS PROF DR ING
IPC: H03K17/64
Filed: 1976-11-11
Abstract: The one-way electronic switch is designed to reduce power losses when switched on and to withstand higher reverse voltages when switched off. A linear or current-dependent inductance is connected into the current-carrying path of the switch to limit the rate of rise of the switch's current at switch on. This inductance draws little or no current once the switch is on and stable. In certain configurations the main current path is shunted by a diode and capacitor circuit.

Title: Air conditioner rotary regenerative heat recuperator - has spirally wound corrugated metal supported hydrophilic layer with staggered corrugations
Inventor: HOENMANN WINFRIED DR ING
IPC: F24F3/14

Title: Diamond core drilling bit - with core catcher of inward deflected sprung tongues in core barrel
Inventor: NYLANDER KARL-ERIK
IPC: E21B25/10
Filed: 1977-04-26
Abstract: A diamond core drilling bit has a core catcher which is integral with the tool barrel. The core catcher consists of several U-shaped tongues which have been formed with the base of the U near the diamond cutting edge.

Title: Thermoelectric breakdown of water - using electrolytic cell with DC supply in which the anode and cathode are sepd. by insulation shield
Inventor: REZNIK SAMUEL DR
IPC: C25B1/04
Filed: 1977-08-03
Abstract: Water is decomposed into H2 and O2 by a thermoelectric process. The water conductivity is raised by the addition of an electrolyte and is located in a device having at least one anode and one cathode. These are separated by an insulating shield. They are subjected to a voltage of 15 to 1000V at a current density of 0.001 to 100 Amp/dm2. The anode and cathode are located at a spacing such that breakdown occurs with the above voltage and current density. The mixture so produced of O2 and H2 will contain some evaporated water and this is subsequently condensed out. The voltage and current bands can be narrowed down. The mixture so released is subsequently ignited and the thermal energy used. Used for creating combustible fuel and purifying seawater.
